2 ObjectivesDiscuss clinical indications of new and emerging psychiatric medicationsCompare and contrast the role of new medications with existing medicationsImplement strategies to learn about new psychiatric medications
7 Iloperidone FDA approved in 2009 Indicated for the treatment of schizophrenia in adultsMechanism of action – primarily dopamine (D2) antagonism with some serotonin (5HT2) antagonismFanapt® [package insert]. East Hanover, NJ;Novartis Pharmaceuticals Corporation; Revised April, 2014.
8 Iloperidone - Efficacy 6-week trial with placebo and risperidone showed superiority over placebo and comparable efficacy of risperidone at 6 weeks4-week trial with placebo and ziprasidone found superiority over placebo and similar efficacy to ziprasidone at 4 weeksFanapt® [package insert]. East Hanover, NJ;Novartis Pharmaceuticals Corporation; Revised April, 2014.
9 Iloperidone – Possible Side Effects Metabolic changes – weight gain, ↑cholesterolNot as significant as other 2nd gen drugsExtrapyramidal symptoms (EPS)QTc prolongationOrthostasis, low blood pressure, and dizzinessRarer side effects – priapism, seizure, agranulocytosis
10 Iloperidone - Dosing Starting dose 1 mg twice daily Target dosage range 6-12 mg twice dailyIncrease by no more than 2 mg twice daily every day until target rangeSlow titration due to increased risk of low blood pressure, dizziness, and fallsMaximum dose of 12 mg twice dailyFanapt® [package insert]. East Hanover, NJ;Novartis Pharmaceuticals Corporation; Revised April, 2014.
11 Iloperidone – Role in therapy New second generation antipsychotic choiceLower risk for EPS and weight gain than other optionsHigher risk of orthostasis, dizziness, and falls especially during the initial titration phaseSlow titration phase and twice daily dosing may be difficult for some patients to work with
12 Asenapine FDA approved in 2009 Indications Treatment of schizophrenia in adultsAcute treatment, either as monotherapy or adjunctive, or manic or mixed episodes of bipolar I disorder in adultsMechanism of action thought to be a combination of dopamine D2 and serotonin 5HT2 receptor blockadeSaphris® [package insert]. Whitehouse Station, NJ;Merck & Co., Inc.; Revised March, 2013.
13 Asenapine – Efficacy in Schizophrenia Short term studiesA 6-week trial comparing asenapine to placebo showed superior efficacy asenapine at 6 weeksA 6-week trial comparing asenapine to placebo and haloperidol showed asenapine to be superior to placebo, but not haloperidol. It also showed no difference between 5 mg twice daily and 10 mg twice daily dosingA 6-weeks trial comparing asenapine to placebo olanzapine showed that asenapine and placebo failed to separate and that olanzapine was superior to bothSaphris® [package insert]. Whitehouse Station, NJ;Merck & Co., Inc.; Revised March, 2013.
14 Asenapine – Efficacy in Bipolar I Disorder MonotherapyTwo 3-week trials of asenapine and placebo showed that asenapine was superior to placebo for controlling acute maniaAdjunctiveA 12-week trial of asenapine or placebo added to lithium or valproic acid showed asenapine was superior to placebo at reducing manic symptoms at 3 weeksSaphris® [package insert]. Whitehouse Station, NJ;Merck & Co., Inc.; Revised March, 2013.
15 Asenapine – Possible Side Effects Metabolic changes and weight gainNot as significant as other 2nd gen drugsEPS – higher rates of akathisiaQTc prolongationSedation or somnolenceHeadacheRarer side effects – agranulocytosis, seizures, and orthostasisSaphris® [package insert]. Whitehouse Station, NJ;Merck & Co., Inc.; Revised March, 2013.
16 Asenapine - Dosing Asenapine is supplied as sublingual tablets Do not swallow tabletsDissolve under the tongueNo food or drink for 10 minutes after doseIndicationStarting DoseDosage RangeMaximumSchizophrenia5 mg twice daily5-10 mg twice daily10 mg twice dailyAcute Bipolar ISaphris® [package insert]. Whitehouse Station, NJ;Merck & Co., Inc.; Revised March, 2013.
17 Asenapine – Role in Therapy Can be utilized in both schizophrenia and bipolar disorderUnique sublingual administrationRelatively small metabolic side effectsHigher rates of sedation and akathisia than other agents
18 Lurasidone FDA approved in 2010 Indications Treatment of schizophrenia in adultsTreatment of depressive episodes in bipolar disorder in adults as both monotherapy and adjunctive therapyMechanism of action thought to be a combination of dopamine D2 and serotonin 5HT2 receptor blockadeLatuda® [package insert]. Marlborough, MA;Sunovion Pharmaceuticals, Inc.; Revised July, 2013.
19 Lurasidone – Efficacy in Schizophrenia Five total trials, all 6 weeks longTwo trials of fixed dose lurasidone vs. placebo showed superior efficacy of lurasidoneOne trial of 40 mg, 80 mg, and 120 mg lurasidone vs. placebo showed that only the 80 mg dose was superior to placeboOne trial of lurasidone, olanzapine and placebo showed that both lurasidone and olanzapine were superior to placeboOne trial of lurasidone, quetiapine ER, and placebo showed both lurasidone and quetiapine ER were superior to placeboLatuda® [package insert]. Marlborough, MA;Sunovion Pharmaceuticals, Inc.; Revised July, 2013.
20 Lurasidone – Efficacy in Bipolar Depression As monotherapyA 6-week trial vs placebo for symptom reduction in bipolar depression showed that both doses of lurasidone studied were superior to placebo at 6 weeksAs an adjunctA 6-week trial of patients who were still symptomatic on lithium or valproic acid were given placebo or lurasidone. At 6 weeks, there was a superior symptom reduction in the lurasidone group vs. the placebo groupLatuda® [package insert]. Marlborough, MA;Sunovion Pharmaceuticals, Inc.; Revised July, 2013.
21 Lurasidone – Possible Side Effects Metabolic changes and weight gainPossibly the most weight and metabolic neutralEPS – akathisia more common than othersQTc prolongationSedation or somnolenceNausea and vomitingRarer side effects – agranulocytosis, seizures, and orthostasisLatuda® [package insert]. Marlborough, MA;Sunovion Pharmaceuticals, Inc.; Revised July, 2013.
22 Lurasidone - DosingFor schizophrenia, starting dose is 40 mg/day with a range of mg/dayFor bipolar depression, starting dose is 20 mg/day with a range of mg/dayAll doses should be taken with a meal of at least 350 calories to improve absorptionDosing is recommended in the evening due to the possibility of sedation and somnolenceLatuda® [package insert]. Marlborough, MA;Sunovion Pharmaceuticals, Inc.; Revised July, 2013.
23 Lurasidone – Role in Therapy Can be utilized in schizophrenia and bipolar depressionHas a very favorable long-term metabolic profileOnce daily dosing is most patient friendlyAppears to be the most rigorously studied of the newer agents

43 Viibryd® (Vilazodone) Considerations for UseTake with foodDose titrationNo dose adjustment for agePregnancy, nursing, or childrenMedication RoleNo clear advantage over SSRIs for depressionW/ food – or decrease  by 50%Titration - 10 mg once daily for 7 days, followed by 20 mg once daily for an additional 7 days, and then an increase to 40 mg once dailyNo human data in preg, lactation or childrenViibryd ® [package insert]. St. Louis, MO; Forest Laboratories, Inc.;Revised December, 2012.
44 Fetzima® (Levomilnacipran) Year Approved2013IndicationMajor Depressive DisorderMore active enantiomer of milnaciprin (approved in 2009 for fibromyalgia)More selective for NE - Tx norepinephrine deficiency symptoms - decreased concentration, lassitude, mental and physical slowing, and decreased self-care.3,4 Some authors claim that individual patients could experience improvement in their social and occupational functioning in addition to improvement in the core symptoms of depression.5Fetzima® [package insert].

45 Fetzima® (Levomilnacipran) Mechanism of ActionSerotonin Norepinephrine Reuptake Inhibitor (SNRI)EffectivenessDecreased depressive symptoms in 8 week trials better than placeboDecreased depressive symptoms in three 8 week RCT trials of outpatients (40-120mg all doses superior)Fetzima® [package insert]. St. Louis, MO; Forest Laboratories, Inc.;Revised July, 2013.
46 Fetzima® (Levomilnacipran) SafetyContraindicationsAllergic reaction, uncontrolled narrow-angle glaucoma, use with MAOIWarningsSerotonin syndrome, suicidality, seizure, mania, bleed, low sodium, sudden discontinuationWarnings not based on evidence directly from levomilnacipranFetzima® [package insert]. St. Louis, MO; Forest Laboratories, Inc.;Revised July, 2013.
47 Fetzima® (Levomilnacipran) SafetyWarnings (cont.)High blood pressure & heart rate, narrow-angle glaucoma, urinary hesitation or retentionDrug interactionsAdverse EffectsNausea, vomiting, constipation, sweating, increased blood pressure & heart rate, sexual dysfunctionThese warnings are based off data with levomilnacipranStrong 3A4 inhibitors like ketoconazole; avoid doses > 80mg/day; other medications which can increase BP & HRNo dose adjustment needed for 3A4 inducers(Other: serotonergic/MAOIs, drugs increasing BP & HR, drugs affecting homeostasis – NSAIDs)Alcohol accelerated drug release from ER capsulesUrinary hestitation & erectile dysfunction were dose relatedAlthough BP avg increase was only 3mmHg and HR was 7 bpm…trials excluded patients with significant CVDFetzima® [package insert]. St. Louis, MO; Forest Laboratories, Inc.;Revised July, 2013.
48 Fetzima® (Levomilnacipran) Considerations for UseAdjust dose for kidney impairmentNo dose adjustment for agePregnancy, nursing, childrenMedication RoleNo clear advantage over SNRIs for depressionNo established effectiveness for fibromyalgia/ painPregnancy – decreased birth weight and possibly mortality in rats at supratherapeutic doses.Nursing – present in rat milkChildren – no dataOnce daily dosing; ER tablet – do not split, etcBoth in-vitro and in-vivo studies found that levomilnacipran exhibited more potency for NE reuptake inhibition than for 5-HT reuptake inhibition at the lowest effective dosage (10 mg/kg). However as the dosage was increased (20 mg/kg and 40 mg/kg), it was equally potent at NE and 5-HT reuptake inhibition. This is in contrast to venlafaxine, which demonstrates a similar, but opposite, effect in terms of potentiation at the 5-HT and NE reuptake pumps.2NNT 6; NNT VNL was 8Fetzima® [package insert].

49 Brintellix® (Vortioxetine) Year Approved2013IndicationMajor Depressive DisorderBrintellix® [package insert]. Deerfield, IL; Takeda PharmaceuticalsAmerica, Inc.; Revised July, 2014.Image from us.brintellix.com
50 Brintellix® (Vortioxetine) Mechanism of ActionSSRIActivity at various serotonin receptorsEffectivenessDecreased depressive symptoms in 6-8 week trials & longer time to recurrent depression in 64 week trial better than placebo5HT3, 1D, 7 antagonism, 1A agonism, 1B partial agonist5mg not effective in 6-8 week trials; took 2 weeks for initial effect and about 4 weeks for full effectShort term studies with outpts and were RCTs; Longterm study was open label with inpts and outptsBrintellix® [package insert]. Deerfield, IL; Takeda PharmaceuticalsAmerica, Inc.; Revised July, 2014.
52 Brintellix® (Vortioxetine) SafetyDrug interactionsAdverse EffectsNausea, vomiting, constipation, dizziness, sexual dysfunctionThe maximum recommended dose of BRINTELLIX is 10 mg/day in known CYP2D6 poormetabolizers. Reduce the dose of BRINTELLIX by one half when patients are receiving aCYP2D6 strong inhibitor (e.g., bupropion, fluoxetine, paroxetine, or quinidine) concomitantly.Consider increasing the dose of BRINTELLIX when a strong CYP inducer (e.g., rifampin,carbamazepine, or phenytoin) is coadministered for greater than 14 days. The maximumrecommended dose should not exceed three times the original dose.Nausea was dose related and resolved after ~ 2 weeksNo changes in weight or vital signs observed in pre-marketing trialsBrintellix® [package insert]. Deerfield, IL; Takeda PharmaceuticalsAmerica, Inc.; Revised July, 2014.
53 Brintellix® (Vortioxetine) Considerations for UseAvoid in severe liver impairmentNo dose adjustment for agePregnancy, nursing, childrenMedication RoleNo clear advantage over SSRIs for depression-10 mg administered orally once daily without regard tomeals. Dosage should then be increased to 20 mg/day, as tolerated, because higher dosesdemonstrated better treatment effects in trials conducted in the United States. The efficacy andsafety of doses above 20 mg/day have not been evaluated in controlled clinical trials. A dosedecrease down to 5 mg/day may be considered for patients who do not tolerate higher doses-Although BRINTELLIX can be abruptly discontinued, in placebo-controlled trials patientsexperienced transient adverse reactions such as headache and muscle tension followingabrupt discontinuation of BRINTELLIX 15 mg/day or 20 mg/day. To avoid these adversereactions, it is recommended that the dose be decreased to 10 mg/day for one week before fulldiscontinuation of BRINTELLIX 15 mg/day or 20 mg/dayDevelopmental delays in rats; no adequate human trials; present in rat milk; no studies in peds; no dose adj needed for geri (like other 2 ad’s)No dose adj for geri, race, ethnicity, (like other ad’s) up to severe renal dys, but unknown with severe hepatic diseaseBrintellix® [package insert].
